Normally the dashboard assets are bundled into Geth via `go-bindata` to avoid external dependencies. Rebuilding Geth after each UI modification however is not feasible from a developer perspective. Instead, we can run `webpack` in watch mode to automatically rebundle the UI, and ask `geth` to use external assets to not rely on compiled resources:

### Static type checking
Since JavaScript doesn't provide type safety, [Flow][Flow] is used to check types. These are only useful during development, so at the end of the process Babel will strip them.
To take advantage of static type checking, your IDE needs to be prepared for it. In case of [Atom][Atom] a configuration guide can be found [here][Atom config]: Install the [Nuclide][Nuclide] package for Flow support, making sure it installs all of its support packages by enabling `Install Recommended Packages on Startup`, and set the path of the `flow-bin` which were installed previously by `npm`.
For more IDE support install the `linter-eslint` package too, which finds the `.eslintrc` file, and provides real-time linting. Atom warns, that these two packages are incompatible, but they seem to work well together. For third-party library errors and auto-completion [flow-typed][flow-typed] is used.
### Have fun
[Webpack][Webpack] offers handy tools for visualizing the bundle's dependency tree and space usage.
